JAMES L. SCROGGINS, SHERMAN, TEXAS, ASSIGNOR OF ONE-HALE To A. S.WALDROP, OF SHERMAN, TEXAS COMPOUND TOOL.

Application filed May 21, 1912, Serial No. 698,734. Renewed February 11,1913.

To all whom it may concern.

Be it known that I, JAMES L. Sonoccrns, acitizen of the United States,residing at Sherman, in the county of Grayson and State of Texas, haveinvented certain new and useful Improvements in Compound Tools, of whichthe following is a specification.

In its broader aspect, the object of this invention is to provide acompound tool of the wrench type, the several parts of the constructionof which so cooperate as to permit of a wide range of usage of thedevice.

As is well known, even under ordinary conditions of work, a mechanicrequires two different species of wrenches which, for the purpose ofdiiferentiation, I herein term a nut-wrench and a pipe-wrench. Toprevent the necessity of duplicating these tools, it has been my objectto combine their features in a single device and to this end it iscontemplated to provide in my invention a stationary, a detachable, anda pivoted jaw member, the latter co-acting normally with the detachablejaw member to hold the same in operative position when using the wrenchparticularly as a nut-wrench, and being susceptible of movement into apredetermined position to cooperate with the stationary jaw member foruse as a pipe wrench.

A still further object of my device is to provide a wire cutting elementon the shank whereby wire may be severed by the pivoted jaw member, andwith the above and other objects in View, this invention consists of theconstruction, combination, and arrangement of parts, all as hereinaftermore fully described, claimed and illustrated in the accompanyingdrawings, wherein,

Figure 1 is a View in side elevation of a wrench constructed inaccordance with my invention; Fig. 2 is a front view of the same; Fig. 3is a rear view; Fig. 4 is a horizontal sectional View of the detachablejaw; Fig. 5 is a view in elevation of the wrench, showing thecooperation of the pipe jaw, the detachable jaw member being omitted toshow more clearly the interlocking parts therefor; and Fig. 6 is aperspective view of the detachable jaw.

Throughout the following detail description and on the several figuresof the drawings, similar parts are referred to by like referencecharacters.

Serial No. 747,799.

Specifically describing my invention, 1 designates the shank of a wrenchhaving one end thereof,-designated as 2, constituting the usual handle.The shank 1 terminates at its other extremity in the fixed or stationaryjaw member 8, which member performs a dual function, as will hereinafterbe more fully set forth.

4: designates a detachable jaw member which, when in operative position,constitutes an off-standing member having formed on its inner side thespaced locking members 5 which are adapted to receive therebebetween theT-shaped lug or projection 6 which is formed on the inner side of thestationary jaw member 3. The jaw member 41 is furthermore formed at oneend with the bifurcated portion 4 between which is received theprojection 7 formed on the stationary jaw member 3 adjacent the shank 1of the wrench. The bifurcated portion 4: is cut away preferably at oneside to conform to the recessed portion 8 on opposite sides of the shank1 and when thus constructed the detachable jaw member is held fromlateral displacement in the use of the invention, it being understoodthat as just described the device constitutes a nutwrench. The jawmember 4 when in operative position, at its outer end, is spaced fromthe fixed or stationary jaw member 8 so that the nut may be received inthe opening 9. It is only necessary in positioning the detachable jawmember A to slide the same longitudinally of the wrench in such a mannerthat the T-shapedi projection 7 is received into the opening between thespaced locking members 5 which conforms to the shape of said projection7.

The shank of the wrench on the side opposite the stationary jaw member 4is cut away on both sides of the wrench so as to form recesses thereinand near the outer portion of the recesses which form a reduced edge 10is pivotally mounted the pipe jaw member 11. The jaw member 11 is formedwith spaced side members 11 through which the pivot 12 passes whenmounted on the shank 1 and said members 11 are curved at their oppositeextremity, where they are also connected by means of the end portion 13.At a suitable point on the edges of the side members 11 of the pivotedjaw member 11 are provided the lugs 14 which are adapted to lockinglyengage in notches 15 formed in the bifurcated end portion 4' of thedetachable jaw member 4. When thus engaged, the detachable jaw member 4:is positively held in position and a spring actuated projection 16 ismounted in the recessed portions of the shank 1 so as to projecttherefrom into engagement with a side member 11 on the opposite side tothe lugs 14 and by this means the pivoted i v membe i p even e rom beeemi iserg ged fr m th de a habl jaw memt is ntemp at that a umb o jaw m ms 4 a to he nrevie d fo a w eath each of aid new m be s bein at similare e tr e ier bu f rmed in 1 amanner that the opening 9 will be ofdifterent es eerdin'e to h euete ry si if ra w th.

The inner edges of the curved porea firs m n i n a W ll ase n d eat remity 3', are preferably serrated in order to facilitate thegripping action on the bjec w h s te'be'ei r Or nserewed- The reducededge 10 is suitably formed with a notch 17 at a point near the pivot 12f he me'v ble jaw m e Said not constituting a wire cutting element. Whendesired to sever a piece of wire the jaw 11 is swung outwardly and saidWire inserted in the notch 17, and by movement of said jaw toward theshank of the wrench, the wire will be easily cut in an obvious manner.

It is further contemplated that the top or. outer side of the detachablejaw member a be formed with a V-shaped recess 18, the edge portions ofwhich are undercut and the function of said recess is to permit a nailto be withdrawn when the head of the latter is inserted in said recess,the shank of the wrench acting as a lever. A second recess. 19 is alsoprovided on the jaw memher 4, so formed as to have a pointed projection19 therein, and the purpose of this recess is to provide a simple meansfor. with draw ng s p s th ke There are numerous advantages of myparticular construction of wrench, among which may be mentioned theelimination of thescrew actuated sliding jaw found in ordinaryconstructions of monkey wrenches which are always, subject to wear andrust, The device also serves for perrmin umero s. n ions as dise esedthe description and much expense may be saved by the same from amanufacturing standpoint.

Having thus described the invention, what is claimed as new is:

l.
